Legal claims defining the scope of protection, as filed with the USPTO.
2. The PCA of claim 1, wherein the identification device comprises one or more of a radio frequency identification (RFID) tag, a memory element, a near-field communication (NFC) device, or an integrated circuit (IC) chip.
3. The PCA of claim 1, wherein the authentication device is a security co-processor that is soldered on the PCB.
4. The PCA of claim 3, wherein the platform attestation file comprises a serial number of an endorsement key certificate corresponding to the security co-processor.
5. The PCA of claim 1, further comprising a baseboard management controller (BMC) disposed on the PCA, wherein the platform attestation file is stored in the BMC.
6. The PCA of claim 1, wherein the identity information comprises a unique identifier associated with the identification device, a derived identifier associated with the PCB, or both the unique identifier and the derived identifier.
8. The PCA of claim 6, wherein the derived identifier is generated based on one or more design parameters associated with the PCB.
9. The PCA of claim 6, wherein the derived identifier comprises a cryptographic hash value generated based on design files corresponding to the PCB.
10. The PCA of claim 1, wherein the platform attestation file further comprises additional identity data comprising one or more of a product name, a serial number, or a name of manufacturer.
11. The PCA of claim 1, wherein the remote server further stores an auxiliary identity data corresponding to the PCB, wherein in the auxiliary identity data comprises one or more of reference images, production records, component marking information, or production test results corresponding to a genuine PCB.
12. The PCA of claim 1, wherein the identity information comprises a first unique identifier identifying the identification device and a second unique identifier identifying the PCB.
14. The computing system of claim 13, wherein the identification device is disposed in a cavity formed in the PCB.
15. The computing system of claim 14, wherein the PCB comprises a plurality of layers comprising a top layer, a bottom layer, and a plurality of intermediate layers, wherein one or more intermediate layers of the plurality of intermediate layers comprise openings, and wherein the one or more intermediate layers when stacked between the top layer and the bottom layer define the cavity within the PCB.
16. The computing system of claim 13, wherein the identity information comprises a first unique identifier identifying the identification device and a second unique identifier identifying the PCB.
18. The method of claim 17, wherein embedding the identification device comprises installing the identification device in a cavity formed within the PCB.
19. The method of claim 17, further comprising generating the platform attestation file comprising the identity information.
20. The method of claim 17, wherein the authentication device is a security co-processor, and wherein cryptographically binding the platform attestation file comprises storing a serial number of a private endorsement key certificate of the security co-processor into the platform attestation file.
21. The method of claim 17, further comprising using the authentication device to protect the PCA.
